Biological Microscope
CX43/CX33
CX3 Series
Comfortable, High-Throughput Routine Microscopy
Comfortable for Long Periods of Routine Microscopy
The CX33 and CX43 microscopes enable users to remain comfortable during routine microscopy. The microscope frame
well fit the hands and the location of the control knobs maximize ergonomics to improve work efficiency. Users can quickly
set a specimen with one hand, while adjusting the focus and operating the stage with the other hand with minimal
movement. Both microscopes also feature a camera port for digital imaging.

Maintain Preferred Observation Conditions with Minimal Adjustments
Uniform Illumination with Consistent Color
Temperature
The color temperature of the CX LED illumination produces
daylight conditions, so specimens can be viewed with their
natural colors. The color temperature is consistent at any
brightness, so users don’t have to spend time making
adjustments when they change brightness. The LEDs have a
long 60,000-hour lifetime in the design value, helping reduce
cost, and the brightness level remains stable throughout the
LED’s life.
Select and Set Your Contrast Level
Users can preserve their favorite contrast by locking the
aperture diaphragm. It stays fixed at the optimally chosen
position if it is accidentally touched while changing slides.
Change Magnification without Adjusting the
Condenser
Users can change the magnification from 4X to 100X without
moving the top lens on the condenser. 2X magnification is also
available by simply setting the objective and the condenser
turret to 2X position.
Excellent Optical Performance for Flat Images
The microscope employs Plan Achromat objectives, which
provide clear images with high image flatness over a wide field
of view. This helps users view specimens clearly and evenly
during routine microscope observations.
Simple Fluorescence Observation
Fluorescence observation is simple and easy. Plug the compact
fluorescent illuminator into the microscope frame for
fluorescence observation. Its LED light source is pre-centered,
and the transmitted illumination is shuttered by simply setting
the condenser turret to the FL position. This reduces
background noise in the fluorescence image from incidental
light coming from the top lens of the condenser.

Remain Comfortable during Extended Usage
Single-Handed Sample Placement
Use Up to Five Objectives
A specimen can be quickly slid in and out using one hand. The
specimen holder opens a little and firmly retains the specimen
during operation. The versatile holder accommodates a variety
of slide types, including a hemocytometer.
For added flexibility, up to five objectives can be supported by
the revolving nosepiece. In addition to general objectives, users
can select a 2X objective for wide area observation or objectives
for phase contrast. These objectives with long working
distances help keep specimens from getting damaged.
Ergonomically-Positioned Focus Knob
The low-positioned focusing knob enables users to make
observations while keeping their hands and forearms rested on
the desk, helping provide comfort. The focusing stopper
prevents a specimen from accidentally hitting an objective when
working under high magnification.
Smooth Magnification Change
The low-positioned revolving nosepiece enables users to quickly
change magnifications with minimal arm movement between
focusing, greatly improving work efficiency during prolonged
use.

Ergonomic Stage and Eyepiece Position
Specimen Holders that Match Your Observation Style
The low-positioned stage is designed to enhance comfort and
reduce fatigue. The stage surface can be widely seen from the
eye point position, which enables users to smoothly set and
check specimens on the stage. The stage knob can be
controlled with just a light touch and can be adjusted at the same
time as the focusing knob, since they are located close together.
Stage accessories improve efficiency when users need to
observe a large number of specimens. With the specimen
holder sheet, a specimen can be freely operated by a finger on
the sheet and can be precisely adjusted using the stage knob.
The double specimen holder can retain a large specimen or two
specimens.
Simplified Fluorescence Observation
Fluorescence observation can be easily set up on the standard
configuration while keeping the eye point the same as other
observation methods. Simply plug the compact fluorescent
illuminator into the back of the microscope frame.

Versatile Applications
The universal condenser offers a variety of observation methods and future upgradability. In combination with the five-position
revolving nosepiece, multiple applications can be covered using the single microscope frame.

CX33 Microscope
Simple polarizing intermediate
attachment/CX3-KPA
Offers polarized observation of urate
crystals and amyloid in combination with a
polarizer and analyzer.
For less demanding requirements using only brightfield and
darkfield, the CX33 microscope is a great option. The lowpositioned nosepiece and stage, focusing lock, specimen
holder, and inward quadruple revolving nosepiece make the
CX33 microscope is well-suited for everyday observations in
one easy configuration.
Eyepoint adjuster/ U-EPA2
Raise the eyepoint position by 30 mm for
added comfort.
Arrow pointer/ U-APT
Insert an LED arrow into your image; great
for digital imaging and presentations.
Dual observation attachment/U-DO3
Enables dual, simultaneous observation of a
single specimen from the same direction with
equal magnification and brightness for both
operators. A pointer can be used to indicate
specific sections of the specimen to simplify
the training process and enhance discussion.
